LONDON — The British property billionaire Christian Candy waged a campaign of harassment against his former friend Mark Holyoake, including threatening to cause his wife Emma a second miscarriage, a London court heard today.

In a witness statement, Emma Holyoake said Christian Candy had threatened her family with violence after a property deal with her husband turned sour. She said Christian had allegedly vowed to "f*** him up", in reference to her husband.

Her statement, filed in the high court and seen by Business Insider, said:

"Mark informed me that Christian had repeatedly threatened him saying such things as he would destroy him and his family, he would 'nuclear bomb his entire world' and would 'f*** him up' in any way possible if he did not do exactly what was asked of him."

Her statement added:

"[Mark Holyoake] told me that Christian had made various threats, but the one that I remember him telling me about is that Christian would put us under so much pressure as a family that I would have another miscarriage."

Mark Holyoake is suing the Candy brothers over a £12 million loan issued by them to fund his project with the Grosvenor Gardens apartment block. The loan required payments of 20% interest a year, and 30% of the net profit once the Grosvenor Gardens property was sold. Holyoake claims he was pressured into repaying £32 million and withdrawing from the project, losing an estimated £100 million in profits by selling to the Candys before completion. Holyoake is suing for alleged blackmail, extortion, and intimidation, according to documents filed with the high court and seen by Business Insider.

The Candy brothers are fighting the case, and deny the allegations. They have yet to tell the court their side of the case.

Emma Holyoake claimed Christian Candy and his wife Emily had disapproved of Nick and Holly's marriage in 2012.

Christian allegedly said: "If she sees me coming she better f***ing cross over onto the other side of the road". Emma Holyoake's own friendship with Valance turned sour towards the end of 2013, she said.

According to the witness statement:

"To say that there was no love lost between Christian and Holly would he an understatement. I don't know the origin of that dislike, but Holly and Christian's wife did not get on of all. In fact Holly told me at a party given by mutual friends in Ibiza in June 2012 [...] that Christian had [said] about her: 'If she sees me coming she better f****** cross over onto the other side of the road' which Holly took to be a threat."

Her statement added:

"At the same party, Holly told me that Christian did not approve of her relationship with Nick and later (at the same party, which was a three-day event) told me that Emily, Christian's wife, had tried to dissuade Nick from marrying her."

According to Holyoake's evidence, Christian Candy "bullied" his brother, something allegedly recounted to her by Holly Valance. Valance allegedly told Holyoake in 2012 that she had found Nick Candy "lain down in the foetal position" and "crying uncontrollably", due to Christian's behaviour. Valance allegedly described Christian Candy as a "rude, dishonest, and a cruel man".

Emma Holyoake cried while being cross-examined in court today.

A spokesman for the Candy brothers said:

"Emma Holyoake has accepted in evidence that her statement is based on information provided to her by her husband whose claims are denied in their entirety. The statement has the sole purpose of causing reputational damage to the Defendants."

The Defendants remain committed to having these matters decided at trial by the Judge."
